Application med J 'anuary so, 1926. Serial noises e.

invention relates to caps or closure devices adapted for use withbottles or other containers.

An object of my invention is to provide an 5 improved form of bottle capwhich may, if desired, be applied to the bottle after the latter hasbeen sealedby an inner cap'or seal 1 andwhich may later be used as atemporary closure for the bottle after the inner seal is removed anddiscarded, and' until the con.-

tents of the bottle have been used up.-

Other objects of the invention and the I precise nature thereof willappear more fully hereinafter.

ln the-accompanying drawings: 7 Figure 1 is a perspectiveview of a capconstructed in accordance with myinvcntion.

Figure 2 same.

is a sectional elevation of the upper end of a bottle with the capapplied thereto, aportionof the cap'being broken away: i i

folded seam formed'in the body of the-cap. The body 5 of the cap isformed from a strip of sheet metal having its ends brought together andconnected by an interfolded seam-(tithe lower end 0f which terminates atthe point 7. Below the point 7, the ends 8 may overlap more or lesswithout being interfolded, thereby adding to the elasticity of the lowerportion 9 of the cap. The upper edge-of the cap is inturned to form .aflange 10. I A top piece 11 fits within the body portion 5 and bearsagainst the fiangelO. This top piece is preferably a. disk made of heavypaper, cardboard, or other suitable fibrous material, of suflicientthickness and stiffness to retain its shape and position within the capunder all ordinary conditions. The top piece 11 fits closely withinthebody portion and is securely held in position by a ring of corrugations12. The top piece is preferably varnished or coated with some suitablewaterproofing material which may be aplied to both the'upper and lowersurfaces 5 thereof. The coating may comprise layers 13 and 1% ofvarnished, waterproof paper,

I Figure 3 is an elevation view showing the Figure 4 1s adetail-"showing the interor the like, which may be appliedto, either orboth the inner and outer faces of the top piece.

In the manufacture of. the cap, the body piece 5 after-being stampedfrom sheet metal is curved to cylindrical formftheendsunited by thell'llel'fOldQd seam 6 and [the upper edge turned to form the'flange 10.The top piece 11 is inserted and the .capis then put on a'beadingmachine and the beadf9 rolled thereon. Simultaneously with the rollingof the bead 9, the corrugations 12 are formed I and dig firmly into thewalls of the disk 11,

so that the latter is securely held in place thereby.

, The cap is adapted for usewith a bottle or container 14. The bottlemay beprovided annular rib unitingthe bead 9 with the body of the cap.When the cap is applied to the bottle, the, ribjIS slips over the bulge17 and snaps into position with the lower edge of the" bead '9, restingon the-shoulder of the bottle formed by the ring 16.

"The cap may serve as an overcapor cover to fit over the. bottle neckand crown cap or other closure with which the bottle'isorigusuallymutilated and destroyed in'opening the bottle. The overcap may then beused asatemporary closure, which is readily removed from timeto time asrequiredfor dispensing the contents of the bottle.

The inside walls of the cylinder or body inally sealed Whenitis desiredtou'se the contents of th e bottle, the overcap is re- ;moved. ,Theoriginalsealing cap is then re- .moved and ordinarily discarded, as itis portion of the cap are preferably coated with an enamel orlacquerfinish, and as; such finish isnot mutilated by threading or otheroperations required in the formation of the cap, it retains its naturalsmoothness and is proof against rust, corrosion, or blackening,

which frequently result from the use of the usual metal caps withcontainers for catsup and various otherinaterials. The inner surface ofthe top portion 11 being provided With a coating of paper or the likewhich is waterproof and rust proof, is also free from the usualcorroding, blackening or other objectionable' action thereon by thecontents of the container.

Modifications may be resorted to within the spirit and scope of myinvention;

:l/Vhat I claim is: i

1. A cap fOl',iJOil-i3l6S or other containers comprising a cylindricalbody portion formed oi sheet metal, and atop portion comprising a diskof fibrous materiahsaid body portion being formed to securely hold thetop portion in position within the body portion prior to and afterattachn'ient to a bottle, and a holding rib at the end of the bodyopposite the top portion, said rib being transversely divided andcircumierentially eizpa'n'sible.

A cap comprising a body portion formed from apiece of sheet metal rolledinto the form of a cylinder and having its ends joined by an interfoldedseam, and a top portion, means tor securing said top portion to the bodyportion at one end thereof, the opposite. end of the body portion beingformed with a circuinterential bead, said seam terminating at a pointspaced above said head, whereby circumferential expansibility is giventhat portion of the body below the seam.

3. Thecombination of a bottle and a cap therefor, said cap comprising atop portion to fitthe top of the bottle and a depending cylindricalportion to surroundthe bottle neck, said cylindrical portion comprisin;-a,

sheet metal piecehaving its ends unitedby an intertolded seam extendingdownward "from the top of the bottle cap and terminating at apoint-spaced above the lower edge of'the cap providingacircumferentially ex pansible strip around'sa-id lower edge, a ribformed in said expansible strip, the neck of the bottle being formedwith an annular bead providing a shoulder against which the lower edgeof the cap rests, and with an annular groove above Faidhead into whichthe rib contracts when the cap is in position on the bottle.

4. A cap for bottles or other containers comprising a body portionformed from a piece of sheet metal rolled into the term of a cylinderand having its ends joined by an interiolded seam, a top portion fixedto one end of the body, said seam terminating at a point spaced abovethe other end of said body permitting lateral expansionqof the bodybelow said point, and an inwardly directed annular rib formed on thebody in said other end.

5. A cap for bottles or other containers comprising abody' portionformed from a piece of sheet metal rolled into the form of a cylinderandhavinp; its ends joined by an interiolded seam, a top portion fixedto one end of the body,said seam terminating at a point spaced above theother end of said body permit-ting lateral expansion of the body belowsaid point, an inwardly directed annular rib formed on the body'in saidother rib.

6. A cap for bottles or other containers comprising a cylindrical bodyportion formed of sheet metal, a top portion comprising a disk offibrous material, said body portion being formed to securely hold thetop portion in position within the body, and a holding rib at the endoil. the body portion opposite the top, said rib being transverselydivided and circumterentially expansible;

7. A cap vfor bottles or other containers comprising a cylindrical bodytormed'otsheet metal, a top portion con1- prising a disk oi fibrousmaterial, said body portion being formed With'an annular flange at oneend thereof against which the top portion rests, meansextendingcircumferentially the body portion to engage the edge ot thedisk and hold it in position, and

.a holding rib at the end of the bodyportion LESLIE n. N; CARVALHO.
